Fyre: About

Fyre is a tool for producing computational artwork based on histograms
of iterated chaotic functions. At the moment, it implements the Peter
de Jong map in a fixed-function pipeline with an interactive GTK+
frontend and a command line interface for easy and efficient rendering
of high-resolution, high quality images.

This program was previously known as 'de Jong Explorer', but has been
renamed to make way for supporting other chaotic functions.

All the images you can create with this program are based on the simple
Peter de Jong map equations:

x' = sin(a * y) - cos(b * x)
y' = sin(c * x) - cos(d * y)

For most values of a,b,c and d the point (x,y) moves chaotically. The
resulting image is a map of the probability that the point lies within
the area represented by each pixel. As you let Fyre render longer it collects
more samples and this probability map and the image becomes more accurate.

The resulting probability map is treated as a High Dynamic Range image.
This software includes some image manipulation features that let you
apply linear interpolation and gamma correction at the full internal
precision, producing a much higher quality image than if you tried to
create the same effects using standard image processing tools.
Additionally, Gaussian blurs can be applied to the image using a
stochastic process that produces much more natural-looking images than
most programs, again without losing any of the image's original precision.
